1. Checked the BF. The primary coil was touching to the secondary coil.Shifted the secondary coil. The behavior of BF became natural.
2. Replaced the blades of FR in the F0 from the BF type + old BF type x2 to the F2 type x2.
3. The height of F0 keystone was set to -19mm with the ballast (25 +5x5 +1.8 = 51.8kg).
4. Measured the rage of FR again (plot). It can move the keystone by +/- 4mm.
5. Tried to move the FR in F3 using the stand alone driver. It didn't work. We found the one side of coil in the stepper motor was grounded; 18Ω bw #1-6pin, 1.9Ω bw #1pin-chamber, 17.6Ω bw #6pin-chamber.
